The 5-winged capsules of Craigia superficially resemble the fruits of Burretiodendron, which has led to confusion. Craigia can be distinguished from Burretiodendron by its petaloid staminodes and the lack of petals. Both species of Craigia are included in the IUCN Red List; C. kwangsiensis is possibly extinct.
